How to read the technical details
Organic carbon describes carbon content; moisture describes water content; and particle size describes how fine or coarse the material is. Higher carbon or lower moisture does not automatically mean a better choice for your plants or process.
¹ Blends: The finished garden blends are specified by ingredients. Carbon, moisture, and particle-size figures for their biochar ingredient should not be treated as figures for the entire blend. See each specification sheet for composition.
Specification notes: Reported ranges are typical and may vary by lot; moisture at analysis is a measured range, while ≤ means “at or below.” Confirm requirements with Wakefield for a specific order.
